Review on MosaicTiles Assorted Glitter Supplies Ceramic by Michelle Langley

The tiles were probably accidentally thrown into a 200g plastic bag and placed in a shipping carton. A US penny weighs 2.5 grams (google it). Surely a tile weighs at least a penny, so there will be around 80 tiles in the pack. One of the photos shows five coasters (tacks), each consisting of exactly 81 tiles (9x9). In the absence of any information (other than 200g) on the number of tiles per pack, I think 81 is a reasonable number. A tolerance of about 1/8 inch grout between tiles means one pack will cover an area 4.74 inches by 4.74 inches square. Which is more like a large coaster or a small coaster. If two packs contained 169 tiles, this would occupy an area of 6.87 inches by 6.87 inches square.
